Dr. Nicolas Gueguen, a psychologist from the University of South Brittany, analyzes the science of attraction and ran the study. In the first part, he asked 46 female students to sit in a room on their own and watch a video of a guy speaking about himself. Half of the women sat in a room with three vases of different flowers and the other half didn’t. The women in the room with flowers consistently found the man more attractive and were more willing to date him.

The second part of the study involved 122 single women, who took turns interacting with the same man for five minutes. Even though he followed the exact same conversational script with every woman, 81% of the women accepted his request for a date in the flowered room compared to merely 50% in the flowerless environment. And you thought flower-power only worked for Mario and Luigi.
